ADUM1201WTRZ55

Overview

The ADUM1201WTRZ55 is a general-purpose digital isolator manufactured by Analog Devices Inc. It features two independent channels with unidirectional signal transmission. The device utilizes iCoupler magnetic coupling technology to provide electrical isolation rated at 2500Vrms. It supports data rates up to 1Mbps and offers a common-mode transient immunity of 25kV/µs. Operating voltage ranges from 2.7V to 5.5V, with a maximum propagation delay of 150ns. The component is housed in an 8-SOIC package.

Feature Summary

• Implements iCoupler magnetic coupling technology for galvanic isolation without external transformers
• Provides bidirectional level translation between 3V and 5V logic domains
• Delivers high common-mode transient immunity exceeding 25kV/µs
• Supports operation across an extended industrial temperature range

Applications

• Industrial process control systems requiring signal isolation
• Medical equipment needing patient isolation barriers
• Power management circuits with isolated feedback paths
• Automotive electronics interfaces

Procurement Notes

Verify the specific suffix designation carefully during procurement. The ADUM1201WTRZ55 variant may differ in moisture sensitivity or packaging specifications compared to standard tape-and-reel versions. Confirm that the received components match the exact ordering part number to ensure compliance with required environmental ratings and handling procedures.

Selection Notes

Select this component when a dual-channel isolator with moderate speed requirements is needed. It is suitable for applications where space constraints favor the narrow SOIC-8 package. Consider the 1Mbps data rate limit and verify that the 2500Vrms isolation rating meets the safety standards of the target system design.

Part Context
